SPECIFICATION forming part of Letters Patent No. 619,631, dated February14, 1899.

Application filed November 2'7, 1896. $erial No. 613,603. (No model.)

To all whom, it may concern:

Be it known that I, BENJAMIN TALBOT, a subject of the Queen of GreatBritain and Ireland, and a resident of Pencoyd, Montgomery county,Pennsylvania, have invented certain Improvements in Gas-Producers, ofwhich the following is a specification.

My invention relates to gas-producers in which carbonic oxid is producedby the distillation and combustion of coal or other fuel in a structurehaving a determinate air-supply, the object of my invention being to soconstruct such a producer as to greatly increase its capacity ascompared with producers as now constructed and at the same time toprovide for the effective breaking up of the clinkers in the hot zone ofthe producer, using by preference for this purpose watercooled pokers orslice-bars.

In the accompanying drawings, Figure 1 is a vertical sectional view of agas-producer constructed in accordance with myinvention; and Fig. 2 is asectional plan view of the same on the line as m, Fig. 1.

In modern iron and steel works it is the accepted practice to use asfuel in the various furnaces gas generated in a separate furnace orproducer, as it is usually termed, these producers usually consisting ofstructures of fire-brick or cylindrical metallic shells lined withfire-brick, into which the coal or other solid fuel is fed from the topthrough a bellhopper. In order to prevent the formation of clinkers andthe caking of the coal in such producers, constant agitation or pokingof the contents of the producer from the top or sides, or both, isnecessary, such agitation being usually effected by means ofmanuallyoperated pokers or slice-bars. This labor is extremelyexhausting, and owing to the poisonous quality of the gas the laborersare frequently overcome by the leakage. Furthermore, the producers mustbe of limited capacity in order to permit the pokers or slicebarsintroduced from the top or sides to gain access to all parts of theinterior of the producer.

In carrying out my invention I make the lower portion of theproducerthat is to say, the portion containing the hot zone whereclinkers are formedof greater diameter or lateral dimensions than theupper portion into which the coal is fed and through which it descendsto said hot zone, so that pokers passed vertically through this expandedportion of the producer can operate close to the wall or lining of theexpanded lower portion of said producer, and thus prevent the formationof adhering masses of clinkers on said lining, the necessary length ofthe poker being only sufficient to reach to the central portion of saidexpanded portion of the producer. This expansion in diameter or lateraldimensions of the lower portion of the producer containing the hot zonealso provides for the use of water-cooled pokers, which can, if desired,be operated mechanically, so as to dispense with the manual labor nowrequired for this purpose.

In the drawings, 1 represents the.lower or expanded portion of theproducer-body,whioh, as shown in the present instance, is of cylindricalcross-section although it maybe square or of other polygonalcross-section, if desired. The portion 1 of the producer is mounted uponsuitable vertical standards or columns 2 and carries a suspendedash-hopper 3, the lower portion of which extends into a sealingpit 4containing water, whereby the escape of any air or gas from the bottomof the ashhopper is prevented.

Resting upon the portion 1 of the furnace is a ring 5, preferablyprovided with one or more channels for the flow of water or othercooling fluid, and upon this ring is supported the upper portion 6 ofthe producer-body, which is of a diameter or lateral dimensionconsiderably less than the portion 1 of the producer. Hence there isbetween the walls of the upper and lower portions of the producer-body aportion of said ring through which can be passed pokers or slice-bars7,.

which can work close to the inner surface of the walls of the lowerportion of the producer, and thereby prevent the formation of adheringmasses of clinkers to said walls. The pokers can also be moved in alldirections through the openings in the ring of the producer, so as tobreak up the clinkers formed in the lower portion 1 of the same, thisportion containing the hot zone in which said clinkers are formed.

To prevent leakage around the pokers, the latter are preferably guidedin universallypivoted carriers 8, mounted upon the ring 5, and as someportion of each poker is always embedded in the incandescent mass offuel in the lower portion 1 of the producer it is advisable to useWater-cooled pokers. Thus in the present instance each poker has anouter tubular casing closed at both ends and having an internal pipe 9,extending from the outerend of the same down close to the inner end,said pipe being of considerably less diameter than the outer tube, sothat water admitted through a tube 10 to the internal pipe will passdown through the pipe and will then rise through the annular spacebetween said pipe and the outer tube and escape from the upper portionof the latter through a flexible tube 11.

To prevent caking of the fuel in the lower portion of the upper section6 of the producer, the latter may be provided with side poke-holes 12for the insertion of pokers or slice-bars of the usual character, or thefuel in the upper part of the producer may be broken up by pokersinserted through suitable openings in the top or cap plate of theproducer.

Having thus described my invention, 1

claim and desire to secure by Letters Patent-- 1. A gas-producer having,a contracted upper body and an expanded lower body with abrupt lateralconnection between the two, one or more poke-holes in said lateralconnection, whereby the poker can act directly upon the fuel in theexpanded lower body of the producer, and a gas-outlet in the upperportion of the contracted upper body of the producer, substantially asspecified.

2. A gas-producer having a contracted upper body and an expanded lowerbody with abrupt lateral connection between the two, pokers mounted inbut free to pass through said lateral connection, so as to act directlyupon the fuel in the expanded lower body of the producer, and agas-outlet formed in the upper portion of the contracted upper body theproducer, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

BENJAMIN TALBOT.
